Give it a few years. After all how will Tesla get that $99 every month for your self driving susbscription?

Your car and fellow road users' cars generally have your life, your passengers' lives, and other road users' lives in its hands while in use.

Well, I see how, especially for people who are close to death and want to provide for their loved ones, the answer to "Your money or your life" might lean in the other direction.

My car probably could be hacked to murder me in secret but frankly I'm not worth expending that kind of access on.

The threat model is really very different.
